JOINT-LOCK FOR STOVE-PIPES.

SPECIFICATION forming part of Letters Patent No, 368,703, dated August23, 1887..

Application filed December 20, 1886. Serial No. 222,097. (No model.)

To aZZ whom it may concern,-

Be it known that I, OWEN B. BLAKESLEE, a citizen of the United States,residing at Burlingame, in the county of Osage and State of Kansas, haveinvented certain new and useful Improvements in Joint-Locks forStove-Pipes; and I do declare the following to be afull, clear, andexact description of theinvention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beingbad to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification;

The special object of the invention is to lock together sections ofstove-pipe, so that they will always remain as placed.

The invention will first be described in connection with the drawings,and then pointed out in the claim.

Figure 1 of the drawings is a side elevation of two sections ofstove-pipe locked together by my invention. Fig. 2 is a detail view inperspective of my locking-piece.

In the drawings, A A represent two pieces of Stovepipe belonging todifferent sections;

B, my locking-piece.

My locking-wire or metallic strip 13 is made somewhat like the oldreaping-hook, being provided with the curved body I), and the arm I)arranged at an angle thereto. In the stovepipes are made two holes, a a,in each, those of one pipe registering with thoseiof the other, so thatthe point I) of the lockingpiece may pass through the four holes andhave the arm resting on the outer section. The strain pro- 3 5 duced bythe weight of pipes being in a line across the curved body I), willeffectually hold the lock-piece in place.

Having thus described my invention, whatI claim as new and of myinvention is- The combination, with two pipes or plates having each twocorresponding holes, a a, of a lock-piece having the body b, curved toconform to the are of the circle, of which the point I) formsa part, andthe straight arm I)", whereby 4 5 sections of pipe may be joinedtogether, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

OWEN 13. BL AKESLEE.
